Question

Quizplus · Accepted Answer

Both definition by subclass and enumerative definition are extensional definitions. Definition by subclass defines a term by listing its subclasses, while enumerative definition lists all the objects that fall under the term. Both approaches rely on listing specific examples to establish the meaning of a term, rather than describing its essential properties or underlying concept.
